PAUL, MINNESOTA, A CORPORATIQ'N 0F MHKNESQTA MErALLfc noon FRAME My present invention has for its object the provision of an improved metallic door frame having detachable, endwise reversible and intel-changeable jambs to permit a door to be hung four different ways in the door frame ,so as to swing either in or out, or from the left or the right. These jambs are provided with two rabbeted door seats and double faced door stops therebetween. Hinged seats are formed in one of the rabbeted door seats of one of the jambs, and by endwise reversing the respective jamb, the door may be hung to swing either in or out, or by interchanging the two door jambs, said door may be hung to swing either from the right or the left.

To the above end, generally stated, the invention consists of the novel devices and combinations of devices hereinafter described and defined in the claims.

In the accompanying drawings, which illustrate the invention, like characters indioate like parts throughout the several views.

Referring to the drawings:

Fig. 1 is a side elevation of the improved door frame and a door hung therein;

Fig. 2 is a fragmentary view in elevation showing the upper left-hand corner of the door frame with the door removed, on an enlarged scale;

Fig. 3 is a view partly in transverse vertical section taken on the line 33 of Fig. 1, on an enlarged scale, and is also a face view of a portion of the door jamb having the hinge seats formed therein,

Fig. 1 is a fragmentary view principally in section taken on the line 4-- 1 of Fig. 3, on an enlarged scale; and i Fig. 5 is a fragmentary detail view in sectiontaken on the line 55 of Fig. 3.

The numeral 6 indicatesa wall diagrammatically illustrated and having a door opening in which the improved door frame 7 is mounted and permanently secured by the customary or any suitable means. This door frame 7 is channel-shaped in cross section, and door casings 8 are integrally formed with the side flanges thereof. lhe upright and horizontal members of the door frame 7 and door casings 8 are each formed from a single sheet of metal, and the side flanges of said frame and the adjacent edge portions of said casings, whichextend at right angles thereto, afford rabbeted seats on each side t} d 7 a 01 1e 001 name or a pnrpose that wi presently appear. 1

A header 1O, chann l-shaped in cross sec tion, has its side flanges seated in the rabbeted seats 9, overlap the side fianges of the hori zontal member of the door frame '2 and are detachably secured thereto by'screws 11. lhe header is formed from a .singlesheet of metal and has two rabbeted door seats 12, and a double faced door stop 13 between said seats.

For each upright of the door frame 7 is a door jamb 1 1- that is channehshaped in cross section with its side flanges extending into the rabbeted seats 9, overlap the upright side flanges of the door frame 7 and are detachably 1 secured thereto by screws 15. Each door jamb 1 1 is provided with two rabbeted door seats 16 of the same width as the door seats 12, and a double faced door stop 17 between said seats 16 of the same width as the door stop 13 (see Fig. The door jambs 1 f extend the full distance from the header 1() to amb, and their end portions are rigidly and permanently secured by spot welding to said jamb, both above and below the seats 18. The intermediate portions of the straps 19 are inwardly offset to receive the respective membersof a pair of'hingcs '20 so that their outer faces are flush with the outer face of the respective door seat 16. These straps-l9 are drilled and tapped to receive screws 21 that detachably secure the hinges to'the respective door jainb 1a.

A hollow metallic door 22, as shown of the slab type, is hung by the hinges 20 in the door frame 7. This door 22 is provided with hinge from. either end of the respective jamb 14 and the door 22 so that said door 22 may be turned end for end and hung to swing either in or out. By removing the screws 15 of one of the door jambs 14, said door jamb may be turned end for end to bring its hinge seats 18 on either side of the door stop 17 so that the door 22 may be swung either in or out, or by removing the screws 15 from both door jambs 1% said door jambs may be interchanged and endwise positioned so that the door 22 may be hung to swing either from the left or the right as well as in or out.

As best shown in Fig. a, the side flanges of the jambs 14, at their longitudinal edges, engage perpendicular portions of the casings 8 at the rabbeted seats 19 and thereby rigidly hold the jambs 14 in position and at the same time make neat and flnisned joints between the door jambs and the casings 8.

What I claim. is:

1. In an integral metallic door frame and easing, jamb members having two rabbeted door seats with double faced door stops therebetween, at least one of said jambs being endwise reversible and detachably applied to continuous faces of the integral frame and casing. v 2. A metallic door frame, the uprights of which are channel-shaped in cross section, door casings integral with the side flanges of the frame, said frame having jambs that are channel-shaped in cross section with their side flanges overlapping the side flanges of the frame and engaging the adjacent edges of the casings as stops, and exposed fastening means detachably securing the ambs to the frame, whereby said jambs may be removed from the frame without disturbing the casings.

3. A metallic door frame, the uprights of which are channel-shaped in cross section, door casings integral with the side flanges of the frame, said frame having jambs that are channel-shaped in cross section with their side flanges overlapping the side flanges of the frame and engagin the adjacent edges of the casings as stops, and exposed fastening means detachably securingthe flanges of the jambs to the flanges of the frame.

1. An integral metallic door frame and casing adapted for permanent attachment in a wall and permitting a door to be hung to either upright side of the frame and to swing either in or out therefrom after the frame is installed and without altering the permanently fixed door frame, comprising in combination jamb members detachably secured to continuous faces of the integral frame and casing and each having registering double faced door stops, and one of said j amb casing, reversible and interchangeable jamb' members having means for detachably securing said members to continuous faces of said frame and easing.

6. An integral metallic door frame and easing rabbeted adjacent opposite sides of said frame to provide continuous faces, and reversible and interchangeable jamb members having side flanges detachably secured to said faces.

7 In an integral metallic door frame and casing, jamb members having laterally projecting side flanges overlapping continuous faces of the frame and casing, and exposed fastening means detachably securing the flanges of the jamb members to said faces, whereby the said jainb members may be removed from and attached to the frame with out disturbing the frame or casing.

In testimony whereof I affix my signature.
